Patent number: 10513241Abstract: The present disclosure relates to an apparatus for vehicle occupant safety during automotive collisions. The apparatus includes a plurality of compression elements rigidly fixed to a first seat belt guide and a second seat belt guide. The compression elements are arranged to resist compressive loading in response to an impact force, such as that experienced during rapid deceleration of a vehicle occupant in an automotive collision. When a pre-determined threshold force has been overcome, the compression elements predictably deform, thus absorbing energy associated with the deceleration. As a result of deformation of the compression elements, additional seat belt length is pulled from the apparatus, thus shielding the vehicle occupant from maximal injury.Type: GrantFiled: December 21, 2017Date of Patent: December 24, 2019Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventor: Colby S.

Patent number: 8955785Abstract: In a webbing winding device, a sub-torsion shaft is inserted from one side in the axial direction of a spool into the spool when assembling the sub-torsion shaft to the spool. Subsequently, by the sub-torsion shaft rotating in the winding direction, movement of the sub-torsion shaft with respect to the spool in the winding direction and in one side in the axial direction is inhibited. Subsequently, by a stopper being fitted from one side in the axial direction into insertion groove portions, movement of the sub-torsion shaft with respect to the spool in the pull out direction is inhibited. Accordingly, since the direction in which the sub-torsion shaft is assembled to the spool becomes only a direction parallel to the axial direction of the spool, the assembility of the sub-torsion shaft with respect to the spool may be improved.Type: GrantFiled: June 15, 2012Date of Patent: February 17, 2015Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Wataru Yanagawa, Yoshiaki Maekubo, Masaru Ukita

Patent number: 8579091Abstract: A dynamic energy management restraint anchor device interfaces with a child seat in a vehicle, engaging common child seat attachment clip features. A device restraint anchor is operable to dynamically extract and permit distortion of load bearing deformable member(s) in order to manage the displacement of, and load transferred through, an anchor connected to a child seat. The device may be further operable to limit or prevent restraint anchor displacement and the distortion of said deformable member(s) under quasi-static load conditions in order to meet motor vehicle static load/displacement anchorage performance requirements applicable to certain anchors. Anchor retraction capability and various interlocking configurations for securing the position of an anchor, before or after having extracted, may be incorporated relative to the energy management device interfacing with both a vehicle and a child seat. An indicator may further be provided to identify the functional state of the restraint device.Type: GrantFiled: November 5, 2008Date of Patent: November 12, 2013Assignee: Ford Global Technologies, LLCInventors: Richard Edward Ruthinowski, Ian Brewster Hall, Parakrama Valentine Weerappuli, Brian Robert Spahn

Patent number: 8348307Abstract: A seatbelt device having a first energy absorbing member with two axial direction end portions attached respectively to a spindle and a lock member and which absorbs energy by undergoing twisting deformation when a load of at least a predetermined value acts on the spindle while the lock member is locked during an emergency. A second energy absorbing member is fixed to the spindle at one end portion and extends through a bend route provided in the lock member. The second energy absorbing member absorbs energy by being pulled through the bend route so as to undergo plastic deformation when the spindle rotates as a result of twisting of the first energy absorbing member. A deformation portion is interposed between a turned back portion of the second energy absorbing member and the spindle.Type: GrantFiled: December 3, 2009Date of Patent: January 8, 2013Assignee: Autoliv Development ABInventor: Kazuhiro Moro

Patent number: 8220735Abstract: An adaptive load limiting seat belt retractor particularly adapted for motor vehicle applications. The retractor provides multiple levels of load limiting through the use of a pair of internal torsion bar elements. The torsion bar elements control the tension force on the seat belt webbing during an impact in a manner which provides desirable crash management characteristics. The retractor can be switched between high and low load limiting modes through activation of a pyrotechnic pretensioner. When the pyrotechnic pretensioner is not activated, the retractor provides a low load level characteristic. Pretensioner activation switches the retractor into a high load level operating condition. A high load limiting level is provided when the pretensioner is not activated if the spindle rotation exceeds a limited level in the low load limiting condition.Type: GrantFiled: December 22, 2009Date of Patent: July 17, 2012Assignee: Autoliv ASP, Inc.Inventors: Bin Wang, Frank Kiiskila, Daniel Webb, Jon E.

Patent number: 8172266Abstract: A seatbelt system for generating electrical energy. The seatbelt system includes a rewinding mechanism, an electrical generation mechanism, a locking mechanism, and a charging mechanism. A first rotational engagement unit of the rewinding mechanism is rotated by the movement of a seatbelt and in turn rotates a second rotational engagement unit. The rotation of the second rotational engagement unit causes the electrical generation mechanism to generate electrical energy. The charging mechanism may charge a battery with the generated electrical energy.Type: GrantFiled: April 29, 2010Date of Patent: May 8, 2012Assignee: Empire Technology Development LLCInventor: Aya Seike
